### MORE? LESS? EQUAL?

One math standard that many children struggle with is the ability to understand what is one more and one less. Let’s see what happens when we hop, sing, and move this standard.

Make a number line on a sentence strip. Use a paper clip to slide to different numbers and the children can see what comes before and after.

Number Line Hop
Draw a number line with chalk on the carpet or use masking tape to make a number line on the floor. Choose different children to hop to a number. What is one less? What is one more?
*Let children roll one or two dice and then hop to that number. What is one more? Less?
*Call two children and ask each to stand on a different numeral on the number line. Which one is more? Which one is less?

Ruler Game
Give children a ruler to use as a number line. Have them point to the numbers as they count on the ruler. Can you find 6? What’s 1 more than 6? What is 1 less than 6?

More or Less Game
Make a grid similar to the one shown. Two children take turns making sets with unifix cubes in the middle section. Their partner has to make sets with “one more” and “one less.”

Counting on a Shoestring
Write numerals 0-20 on a cotton shoestring with a permanent marker. Insert a bead. Children move the bead as they count. They can clearly see what is one more and one less.

Ten Little Friends
Ten little friends (Hold up fingers.)
Went out to play (Wiggle.)
On a very bright
And sunny day.
And they took a little walk.
Walk, walk, walk. (Walk fingers in front of your body.)
And they had a little talk.
Talk, talk, talk. (Put fingertips together.)
